Urmhumhain

Urmhumhain, known in English as Ormond or East Munster, was an earldom of Middle Ages-era Ireland that existed in what is now County Tipperary, County Kilkenny, and County Waterford. The region was once ruled by the Norse Vikings, only to be reconquered by the Irish rulers during the course of the 11th and 12th centuries. "Ormond" became a hereditary title within the Irish aristocracy in the following centuries, and Earls of Ormond were created by England into the 17th century.
